Application June 20, 1930, Serial No. 462,637 6 Claims. (01. 2204.0)

This invention relates to a structurally and functionally improved closure capable of use in numerous different associations but primarily intended for, employment in connection with ret is an object of the invention to provide a device of this character which under normal conditions will substantially seal a receptacle in such manner that entrance to and escape from the receptacle body by other than deliberate actuation of the parts, will be virtually precluded and in which, moreover, when it is desired to obtain access to the receptacle, this may be accomplished with minimum efiort. A further object of the invention is that of providing a closure particularly intended for association with a waste receding receptacle and in which the closure will open in virtually. automatic manner and will thereupon automatically return to the receptacle sealing position. V

A still further object of the invention is that of furnishing aclosure in which the parts may read ily be adjusted so as to compensate for wear and/ or to properly correlate the parts so that they may cooperate to obtain the best possible results.

Another object is that of providing an apparatus of this character in which the waste receptacle is normally supported within an outer covering thus preventing the escape of gases or waste from the receptacle but which nevertheless allows easy access to the waste receptacle and provides forthe ready removal of the same.

A'further object of the invention is that of furnishing a closure which may be readily adjusted for cooperation with various sizes of waste receptacles.

.Still another object of the invention is that of providing a waste receptacle and closure in which the waste may be readily removed from the receptacle with freedom from accompanying inconvenience and dirt.

Additional objects of the invention are those of providing a structure of this nature which will embody relatively few parts each individually simple and rugged in construction. These parts being capable of ready assembly and application to either old or specially designed receptacles to provide a purpose operating over long periods of time with freedom from difficulty.

With these and other objects in mind, reference is had to the attached sheets of drawings illustrating practical embodiments of the invention and in which,

Fig. '1 is a partially sectional side view of one form of closure and. receptacle.

Fig. 2 is a view taken along the lines 22 in Fig. 1.

Fig. 3 is a cross sectional side view of another form of receptacle while;

Figs. 4, 5 and 6are sectional side views of three forms of closure members. 7

In Figs. 1 through 4 the'numeral 10 indicates a receptacle of any desired material and configuration and upon which a cap member is disposed.

Obviously, as will hereinafter appear to those skilled in the art certain parts of the hereinafter described construction might be formed integral or fixed with respect to the receptacle body. However, for convenience in manufacturing, as well as with a View to economy and ready separation of the parts when necessary it is preferred that the cap and its associated structure be formed'as shownto be wholly removable from the receptacle body.

Enclosing the receptacle body is an outer cov ering 11 which is mounted on a base 12 and is provided as shown in Fig. 2 with a hinged door 13. This door is secured to a plate member 14 which 'in turn pivoted as at 15 to one side of the base.

Additionally secured to the base member are two or more hollow sleeves 16 in which are disposed rods 17. These rods may be lowered or lifted with respect to the tubes by adjustment of the thumb screws 18. Mounted on the rods 17 by means of, for example, bolts 19 is a closure member 20.

When it is desired to correlate parts in operating position the hinged door of the outercovering is opened and the receptacle body is placed on the plate associated with the door. Then the door is closed carrying with it the receptacle body. It is also apparent that the plate might be dispensed with and the receptacle body merely placed within the outer covering after the door had been opened.

After the receptacle body is within the outer covering the closure member is lowered by means of adjustment of the thumb screws until it comes to a position of rest in contact with the upper v edge of the closure member thus afiording air tight seal of the parts.

With a view to quickly and conveniently emptying the receptacle body once it has been removed from the outer covering, a removable tray 22 as shown in Fig. 3 is provided. This tray has a handle 23 which is grasped by the aperture with one hand and drawn upward while the receptacle is held with the other hand.

This results in a, quick and complete removal LL10 of the contents of the receptacle with very little accompanying litter.

As to the construction of the closure member Figs. 4, 5 and 6 show a form of member provided with a ring 24 which has a funnel shaped abutment 25 associated therewith. This abutment further tends toseal the closure with respect to the receptacle body and permits the closure to be used in association with receptaclebodies of different diameters. Supported above the ring is a closure element in the form of a truncated cone 26 which however might be made in any suitable shape. A cross member 27 is carried by the ring and mounted thereon is an upright post 28. In Fig. 4 this post carries a resilient member 29 which may be formed of rubber or other suitable material while in Figs. 5 and 6 the member is in the form of a coiled spring 30. In Figs. 4 and 6 the resilient member is secured to the cone by fastening it to a projection 31 which extends downwardly from the cone top. In Fig. 5 the top of the coil spring is enclosed in a casing 32 which in turn is disposed within a sleeve 33 formed in the cone top. Adjustment of the parts is pro- .vided for by means of set screws 34 and the cone may be raised or lowered with respect to the ring.

In each instance the cone has an inwardly extending lip at its lower edge and is provided with a sealing member 35 which is secured to its circumference at this point. This sealing member may be formed of felt, rubber or other likely material and has wiping contact with the ring. As shown in Fig. 5 to still further insure an air tight seal a further sealing element 35 is secured to the upper face of the ring and engages the indented lip of the cone member.

From the foregoing it will be understood that among others the specific objects of the invention as specifically aforenoted are achieved. It is apparent that. numerous changes in construction and rearrangement of the parts may be resorted to without departing from the spirit of the invention as defined by the claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is 1. A waste receptacle including a base, a plurality, of expansible supporting members associated with said base, a receptacle body adapted to be positioned on said base between said supporting members, a ring secured to the top of said supporting members and adapted to be positioned. in contact with the mouth of said receptacle body and a universally movable closure so I member supported by said body and positioned above said receptacle body to normally seal the same.

2. A waste receptacle comprising a base, telescopic supporting members carried by said base, means for securing said members at any desired height, a receptacle body adapted to be positioned on said base between said supporting members and a universally movable .closure member secured tosaid supporting members and normally sealing the opening to said receptacle body.

3. A waste receptacle comprising a receptacle body, a ring adapted to be positioned in contact with the upper edge thereof, a closure member carried by said ring and centrally pivoted for universal movement with respect thereto and said ring being obliquely disposed with respect to the side wallsof said receptacle body so as to maintain sweeping contact with said closure member as the latter is swung from closed to open position.

4. A waste receptacle comprising a body por; tion, a ring formed at the top thereof, a closure for cooperation with said receptacle and carried by said ring, said closure being adapted for uni versal movement with respect thereto and said ring being positioned in tangential relationship to the path of travel of. the edges of said closure as the latter is moved from closed to open posiconstant sweeping contact with the same.

5. A waste receptacle comprising a receptacle body, a closure member for cooperation there with, a support mounted on said bodma tubular rubber mounting member carried by said support, the upper end of said tubular member forming the sole connection between said closure and said receptacle body whereby the former has substantially universal movement with respect to the latter.

6. A waste receptacle comprising a receptacle body, a closure member for cooperation therewith, a tightly wound coiled member carried by said receptacle body and extending upwardly therefrom to couple said closure member thereto,
